What to Expect

Dialed-In Chemistry for Long Island Pools

Pool chemistry on Long Island changes fast — heavy rain, heat waves, tree debris, and heavy bather loads all chew through sanitizer. On each visit we test your key parameters on site, dose chemicals based on actual readings and pool volume, and log the results so we can track trends over the season. We protect your plaster, vinyl, and equipment by keeping levels in range instead of chasing problems with guesswork. If you’re a DIY owner, we’ll tell you exactly what we added and what to watch between visits. If you’re on our weekly or seasonal plans, chemical service is the backbone that keeps the rest of your maintenance running smoothly.

What’s Included

  • On-site water testing for chlorine, pH, total alkalinity, stabilizer (CYA), and often calcium/salt.
  • Calculated chemical dosing based on pool volume and current readings (no “dump and hope”).
  • pH and alkalinity adjustments to protect surfaces, heaters, and salt cells.
  • Sanitizer management (tabs, liquid, or salt system support) targeted to your system.
  • Stabilizer (CYA) checks and corrections to match your pool’s sun exposure and use.
  • Light clarifier or specialty chems as needed to help keep water clear and polished.
  • Quick visual check of the equipment pad and pressure gauge so we’re not dosing into a system that isn’t circulating properly.
  • Simple written or texted summary of what we added, current readings, and any recommendations.
  • Option to fold chemical visits into a broader weekly or seasonal service plan.
  • Note: This is a chemical-focused service. Skimming, brushing, and vacuuming can be bundled with full weekly service. Pool Chemical Service starts at $125 + tax; larger pools and specialty chemicals are quoted based on actual needs.

Pool Chemical Service — FAQs

How often should I schedule chemical service?
Most Long Island pools do best with weekly or bi-weekly chemical checks during the season, depending on bather load, sun exposure, and equipment. We’ll recommend a schedule after seeing your pool, but we can also do one-time visits if you just need help getting levels back on track.
Are the chemicals included in the price?
Standard balancing chemicals used during the visit are covered under typical Pool Chemical Service pricing. If your pool requires unusual amounts of chemicals or specialty products (for example, heavy metal removal or serious correction work), we’ll explain that and price it clearly before proceeding.
Do you also brush and vacuum the pool?
Pool Chemical Service is focused on testing and balancing your water. Brushing and vacuuming are included with full weekly or seasonal service. If you’d like us to handle everything, we can quote a plan that includes cleaning plus chemistry so you never have to think about it.
I already have weekly service. Do I still need chemical service?
If you’re already on our weekly program, chemistry is built in. Chemical-only visits are ideal if you self-clean the pool but don’t want to manage the water testing and dosing. We’ll help you decide which setup makes the most sense for how you use your pool.
Can you help me understand my test kit or salt system?
Yes. During a visit we can walk you through your test kit, explain which numbers matter most, and show you how to read your salt or automation panel. Even if we’re handling the chemistry, we want you to feel confident about what’s happening in your water.
